Hydrogen-bond donor type and molar ratio regulated eutectogel properties. • Fructose-based NADESs improved texture and nonlinear rheological behavior. • Hydrogen bonding and hydrophobic interactions stabilize the gel network. • NADESs induced protein rearrangement and molecular association in the gel matrix. Natural deep eutectic solvents (NADESs) have attracted increasing attention as green and tunable media for constructing functional biopolymer gels. However, the composition-dependent regulation of protein–polysaccharide gel networks by NADESs remains unclear. In this study, NADESs were prepared using choline chloride as the hydrogen bond acceptor and glycerol, fructose, or lactic acid as hydrogen bond donors (HBDs) at different molar ratios (1:1, 1:2, and 1:3). These NADESs were subsequently combined with soy protein isolate (SPI) and xanthan gum (XG) to fabricate nine eutectogels. The choline chloride–fructose (C-F) NADESs exhibited the highest viscosity and the choline chloride–lactic acid (C-L) NADESs provided the strongest acidic environment. The HBD type and molar ratio markedly regulated the microstructure of the eutectogels. Hydrogen bonding and hydrophobic interactions were the main forces stabilizing the eutectogel network to restrict water mobility, while reductions in free sulfhydryl content and surface hydrophobicity indicated protein rearrangement and molecular association within the gel matrix. The C-F NADES at a molar ratio of 1:3 significantly improved the hardness (53.20 ± 0.85 g), cohesiveness (0.70 ± 0.00), gumminess (31.23 ± 0.64 g), and adhesiveness (47.87 ± 0.84 g s) of the eutectogels, while also enhancing their viscoelastic properties and resistance to nonlinear deformation. This study offers a feasible NADES-based approach for designing food-grade protein–polysaccharide eutectogels as tunable soft matrices for the food industry.

The purpose of this study was to characterize the electrostatic complexation between scallop Patinopecten yessoensis male gonad hydrolysates (SMGHs) and κ -carrageenan/xanthan gum (KC/XG) within pH 12–1 at different hydrolysate/polysaccharide ratios (9:1–1:9) and to investigate the influence of pH and ratios on gelation and microstructural properties for widening the application of marine-derived source. According to the phase diagram of SMGHs/KC/XG, pH c hold a constant value around pH 8.5, pH φ1 gradually shifted from 4.2 to 2.8, and pH max fluctuated within 2.4-1.4 as ratios decreasing from 9:1–2:8. Additionally, SMGHs/KC/XG showed higher gel strength in acid condition, as decreasing pH promoted the electrostatic attractive interactions within positively charged patches in SMGHs and negatively charged sulfate and carboxyl groups in KC/XG causing more tightly packed structures formation. Moreover, decreasing ratios from 9:1 to 3:7 could further enhance the gel strength of SMGHs/KC/XG, ascribing to the stronger gelation ability of polysaccharides and enough neutralization. Moreover, SMGHs/KC/XG exhibited well-organized microstructures with smaller pore sizes, denser and more homogeneous networks at more acid domains, supporting stronger gel strength. Therefore, this study provides theoretical and methodological basis for designing novel SMGHs/KC/XG hydrogels with considerable gel strength and microstructures through understanding the complex coacervation at different pH and ratios.

In this study, colon-targeted nanoparticles were fabricated using zein and xanthan gum (XG) as carriers (ZX) via anti-solvent precipitation and electrostatic deposition to encapsulate giant salamander protein hydrolysate (SPH) or its Maillard reaction (MR) products (SPHX). Their alleviative effects on ulcerative colitis (UC) were investigated. Zein and XG primarily formed nanoparticles through hydrogen bonding, hydrophobic interactions, and electrostatic interactions. After encapsulating SPH or SPHX, the resulting nanoparticles exhibited smooth, spherical morphologies with particle sizes below 200 nm and good stability. Compared to SPH-loaded nanoparticles (ZSPHX), those loaded with SPHX (ZSPHXX) exhibited superior in vitro sustained-release properties, enhanced in vivo colitis-targeting ability, and improved cellular reactive oxygen species (ROS) scavenging capacity. The encapsulation of ZX enhanced the cellular uptake of SPHX. In a dextran sulfate sodium (DSS)-induced UC mouse model, dietary intervention with ZSPHX/ZSPHXX (especially ZSPHXX) alleviated UC by exerting anti-inflammatory and antioxidant effects, repairing intestinal barrier damage, and modulating the gut microbiota. Finally, bioactive peptides were isolated from the intestinal contents of mice treated with ZSPHX/ZSPHXX and screened to evaluate their UC-alleviating effects. The results showed that the peptide AVFPSIVGR, identified in the ZSPHXX group, exhibited markedly stronger ROS scavenging activity than IGAPDMAFPR, which was identified in the ZSPHX group. This enhanced antioxidant capacity may be a primary factor contributing to the superior UC-alleviating effects of SPHX. This work provides a simple strategy for constructing a bioactive peptide UC colon targeted delivery system and preliminarily reveals the potential mechanism of MR enhanced peptide UC alleviation.

A humic acid-gelatin (HA-Gel) hydrogel, a gallic acid-xanthan gum (GA-XG) hydrogel, a HA-Gel/GA-XG hydrogel, and superabsorbent polymer (SAP) of HA-Gel/GA-XG/polyacrylamide (PAM) hydrogel were synthesized using electron beam irradiation method. The capability of synthesized hydrogels in loading and controlled release of fulvic acid (FA) was studied. The chemical and physical structure of sorbents was confirmed by various analyses. The effect of irradiation dose on mechanical properties, gel percentage, swelling, and absorbency under load (AUL) of the sorbents was investigated. By changing the hydrogel structures into the SAP form, its swelling capacity was increased from 37 to 320 g/g. Both hybrid hydrogel and SAP were reusable for up to 7 cycles. The maximum fertilizer loading capacities for SAP and hybrid hydrogel were 402.1 and, 175.5 mg g −1 , respectively. In comparison to hydrogels, the SAP showed a slower FA-release performance. Thus, in soil media, 86 % of FA was released in 15–20 days from the hybrid hydrogel while with the SAP, 81 % of FA was released in 30–35 days. The significant improvement in the growth of fodder corn treated with FA-loaded SAP in the greenhouse media in comparison to the control groups showed the effective performance of the designed SAP, favoring its practical applications.

Thermochromic wood-based phase change material (TWPCM) is a temperature-responsive, smart material that actively manages thermal energy in response to ambient temperature fluctuations. The material has become a central focus in research on thermal energy storage and temperature sensing in recent years. A key research direction is the incorporation of delignified veneer impregnated with thermochromic phase change material (TPCM) into a multi-layered structure to enhance the thermal energy storage capacity of TWPCM. This study fabricated two thermochromic laminated veneer cellulose-based alizarin/stearic acid/nano‑silicon dioxide/hexagonal boron nitride composites encapsulated with xanthan gum and wood wax oil films, designated as TWPCM1-XW and TWPCM2-XW. Herein, a TPCM with superior latent heat value (215.9 J/g) was fabricated by compositing alizarin and stearic acid. TWPCM1-XW and TWPCM2-XW can obviously change color within a temperature range of 52–74 °C and revert to primary color at temperatures below 45 °C within 60 min, their latent heat values can reach 133.8 J/g and 163.4 J/g. Therefore, the resulting composites exhibit superior temperature-responsive and thermal-storing capabilities. Moreover, the materials demonstrate outstanding long-term applicability and stability in their capabilities. Additionally, the chemical structures of the synthesized materials were elucidated, and their thermochromic and thermal-storing mechanisms were explained for developing the smart material.
